초록
In this paper, we describe a FIDO universal authentication system based on a Blockchain that can share the user's FIDO authentication information between the application services of multiple domains without the use of a server. In addition we provide a method to query the FIDO authentication information of the user recorded in the Blockchain using only the user's service ID. Therefore, even if the user executes the FIDO registration process only once, the user can use the FIDO authentication service of another application service without repeating an additional FIDO registration procedure, and the service provider can securely share and utilize the FIDO authentication information of the user without the use of a trusted third party, thereby lowering the deployment and maintenance costs of the FIDO server.
